Arduino Nano Bluetooth Transmitter

Was able to connect my Radiopopper Nano Transmitter to a Sony A7 without having to jam it in there. Working like a charm. Also attached the Radiopopper to this Vello, Vello to a Godox X1Ts transmitter, which is then plugged into an A7, and everything still worked. So yay.

Nano receiver goes with the Nano transmitter. It also goes with me whenever I take my flash gear. My recommendation: Don't leave home without it.

I first got one of these for my laptop at work when I started having an entrapped ulnar nerve and wanted a more ergonomic workstation. At first, I tried a Microsoft bluetooth mouse which cost more and would constantly disconnect and require setting up so I did a little research and got the M310. One reason I wanted bluetooth was because the last time I bought a wireless mouse/keyboard (also from Logitech), the receiver was huge and had to be hidden. It also had very low range. To my surprise, the nano receiver with the new M310 is really small - nano if you will, but has much more range than the old style wireless mice. Just for giggles, I was trying it across the room and it still worked. I just leave the nano receiver in the USB port of my laptop all the time and it still fits in my bag. While I was going through painful cortisone injections which did little to help my gimp wrist, I was also happy to use this mouse on either left or right hand as it works both ways (giggity). It's really an elegant design. It's also very light, uses only one AA battery, and battery life is about a year. I liked it so much that now that my wrist is better due to stretching exercises I found on youtube from doctors (which may or may not be legit), I got one for my desktop workstation too which up till then had a wired mouse. It's time to evolve. I'm curious whether the receiver/mouse pairings can be updated in case one or the other is lost.

Works great with all my peripherals (mouse, hard drives, Arduino, usb key ...)

I love this bluetooth transmitter! I lets me use ANY device with an earphone jack to play good music through my good sounding bluetooth speaker. It reconnects automatically too, so all I have to do is turn the devices on and listen. Kudos!

I'm using this to connect my rear projector and sound system wirelessly. I was using so far bluetooth based transmitter receiver which was providing low sound quality lagging and breaking. This one works simply out of the box, no setup needed, and quality is high. The only down side is that some simple audio connectors are missing, but I used those of my previous set.

Highly versatile and compact Bluetooth Receiver/Transmitter with built-in DAC. It has separate optical input and outputs and a dual-use coax line. The Bluetooth connectivity is solid but it might take a few tries with older Bluetooth equipment. Once you're connected, it stays connected. Highly recommended!

Paired easily to my bluetooth transmitter then paired to my other Philips speaker very easily. Good range and great sound

When teamed with a BlueSENSE Bluetooth audio transmitter, I've got great sound anywhere in my house. Easy to set up and great sound with my Yamaha receiver and CD player!

[This review was collected as part of a promotion.] Set up was fairly easy and I was able to pair different types of Bluetooth headphones so that's a great win. The sound will obviously vary depending on the Bluetooth speakers or headphones you are using. I didn't notice any latency but your results could be different to mine. As you can see from the images that I have added the transmitter is very minimalistic and almost takes up no space at all. The transmitter will do only that transmit. For volume controls, you will have to rely on the volume control or your Bluetooth device.
